Disassembly
  
•
Use fender covers to avoid damaging painted surfaces.
•
To avoid damaging the cylinder head, wait until the engine coolant temperature drops below normal temperature (20°C [68°F]) before removing it.
•
When handling a metal gasket, take care not to fold the gasket or damage the contact surface of the gasket.
•
To avoid damage, unplug the wiring connectors carefully while holding the connector portion.
  
•
Mark all wiring and hoses to avoid misconnection.
•
Turn the crankshaft damper pulley so that the piston of No. 1 cylinder is at TDC (top dead center) on compression stroke.

Inspection
1.
Using a gasket scraper, remove all the gasket material from the top surface of the cylinder block.
2.
Using a soft brush and solvent, thoroughly clean the cylinder block.
3.
Inspect the top surface of cylinder block for flatness.
Using a precision straight edge and feeler gauge, measure the surface contacting the cylinder head gasket for warpage.
Flatness of cylinder block gasket surface :
Less than 0.05 mm (0.0020 in) for total area
Less than 0.02 mm (0.0008 in) for a section of 100 mm x 100 mm (3.9370 in x 3.9370 in)

4.
Inspect the cylinder bore.
Visually check the cylinder for vertical scratchs.
If deep scratchs are present, replace the cylinder block.
5.
Inspect the cylinder bore diameter.
Using a cylinder bore gauge, measure the cylinder bore diameter at position in the thrust and axial direction.
Cylinder bore diameter :
77.00 ~ 77.03 mm (3.0315 ~ 3.0327 in)

Reassembly
1.
Install in the reverse order of disassembly.
  
•
In case the cylinder block is replaced with a new one, select the proper crankshaft main bearing and the piston according to the crankshaft journal bore mark and the cylinder bore mark on the cylinder block.
